Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single panel multi-antenna array is used, then the device complexity is reduced, but the horizontal coverage is limited to a single sector and cannot achieve full 360-degree coverage
Solution Approach 1:
The antenna system is divided into multiple independent antenna arrays, each capable of covering a specific sector. These segmented arrays can be independently controlled and oriented to different directions, enabling the system to achieve comprehensive 360-degree coverage while maintaining manageable complexity in each individual array unit.
2Device complexity
If a fixed number of sectors is configured, then the device complexity is reduced, but the adaptability to changing user distribution and service volume is poor
Solution Approach 1:
The sector configuration is made dynamic rather than fixed. The system can automatically adjust the number of sectors and their boundaries based on real-time user distribution patterns and service volume requirements. This dynamic adaptation allows the antenna system to optimize resource scheduling flexibility while managing complexity through automated control mechanisms.
3Area of stationary object
If multiple antenna arrays pointing to different orientations are used to achieve 360-degree coverage, then the horizontal coverage area is improved, but the device complexity increases
Solution Approach 1:
Each antenna array in the system is designed with multi-functionality, capable of serving multiple sectors and being oriented to different directions as needed. This universal design allows the same array structure to fulfill multiple coverage requirements, reducing the need for specialized arrays for each direction and thereby managing overall system complexity while achieving comprehensive coverage.

AI summary
Embodiments of the present invention disclose an antenna system and an antenna system adjustment method. A barrel directional antenna array is formed by M directional antenna arrays, the barrel directional antenna array horizontally covers a 360-degree sector, and M is an integer greater than or equal to 3. The method includes: obtaining a first service volume in the 360-degree sector, where a quantity of sectors in the 360-degree sector is a first sector quantity; determining a second sector quantity based on the first service volume; and dividing the 360-degree sector based on the second sector quantity. The embodiments of the present invention further provide an antenna system, including a barrel directional antenna array, a radio frequency transceiver, and a baseband signal processing and control unit. Based on the barrel directional antenna array, the antenna system can adjust the quantity of sectors in a 360-degree range based on a change in a service volume in the 360-degree sector, so that an adjusted sector service capacity threshold can accommodate the service volume in the 360-degree sector. In this way, resource scheduling flexibility is improved.
